Abstract

Static and dynamic code analyses are seamlessly, iteratively performed. A software analysis tool integrates the results of dynamic and static analysis and iteratively utilizes results from a previous analysis, or analyses, to augment a current analysis. During a debugging process, information collected at runtime is integrated with static code analysis results. This information is generated and stored as part of the results of the testing and debugging processes. The stored information is subsequently utilized to provide improved analysis results. The software analysis tool eliminates the need for software developers to separately perform static analysis and dynamic analysis.

Iterative static and dynamic software analysis
Technical field
The present technique field relates generally to computing system, and relates more specifically to be used for the software development of computing system.
Background
Typical software analysis tool provides statically and the ability of independent analysis software code dynamically.By as technology such as data flow analysis, value traces, static analysis in can authentication code correctness problem and needn't actually carry out this code.Yet static analysis is subjected to can be by the restriction of the information that obtain the static check of binary code through compiling.Performance analysis for example can provide, about sequential with distributed information such as how many storeies.During software development process, the software developer carries out static analysis and performance analysis usually independently, attempts being applied to the result of an alanysis another kind of.
General introduction

The detailed description of illustrative embodiment
During debug process, integrated static state and dynamic software analysis result.The information and the static code analysis result that will collect when operation integrate.This information generates as the spin-off of test and debug process, and is arrived dish by persistent storage in an example embodiment.Utilize institute's canned data to provide subsequently through improved analysis result.
In an example embodiment, when making up, call static analysis.In its original state, regulate static analysis and come minimum noise.That is, if information not sufficiently complete guarantee high determinacy result (or not existing fully), then will can not analyze.As the spin-off that makes up code, this application program is carried out plug-in mounting (instrument) come when moving, to collect specific tolerance.Whenever this information is (to comprise the debugging scene) and dynamically collect what the user ran application.In this example embodiment, when operation, dynamically collect particular data and its persistent storage is arrived storage.During aasubsequent staticaanalysis, recover this information and staticaanalysis results is refined as one group of low noise, high value message and/or enables the brand-new analysis that takes place statically, but but this analysiss is only possible in the tolerance time spent of dynamically collection with it.
For example, in an exemplary scenario, static analysis tools comprises in the detection object code, or checks the inspection of the ineffectivity among the IL (intermediate language) under the situation of managed analysis.This inspection is not enabled acquiescently, because may detect hundreds of positions this ineffectivity pattern and, in most of the cases, solve any single violation and can not produce significant performance gain, and therefore be unworthy the risk that spended time is repaired to be increased introducing code defective and increase.In this exemplary scene, when making up, code is carried out plug-in mounting write down each method or the quantity of calling that function took place.The user carries out this code, and collects these tolerance.In subsequent analysis signal (gesture), excite above-mentioned ineffectivity to detect to a method and check.Static analysis phase is checked the evaluating objects method in the storage vault, and writes down it and frequently called with respect to other the method/function in this application program.This static analysis inspection presents violation to the user, because definite now, if address this problem then may produce significant performance gain.
In another exemplary scene, there is the inspection of interested some things of checking point of invocation.For example, this inspection can attempt determining whether point of invocation will remove quoting a parameter.If then the static check device can warn the user that who has transmitted possible null term to this point of invocation provablely, this can cause collapse when operation.This inspection can not the analyzing virtual point of invocation, because the virtual statement of a point of invocation quoting method.That is, the IL vague generalization that comprises definition is quoted; It does not quote any specific specific implementation that this definition is provided.Run time between, detect to realize virtual method specific subclass and with it with IL in the general reference that exists carry out related.During aasubsequent staticaanalysis, above-mentioned inspection can be retrieved the specific implementation that is associated with general point of invocation provablely, and makes this specific implementation stand its inspection.
Fig. 1 is the process flow diagram that is used to provide the example process of ofaiterative, dynamic and staticasoftware analysis.In an example embodiment, as shown in Figure 1, carry out dynamic software analysis also expands this dynamic software analysis with previously stored staticaanalysis results result.Start dynamic software analysis in step 12.Carry out dynamic software analysis (DA) in step 14.Dynamic software analysis can be carried out by any suitable dynamic software analysis instrument.For example, performance analysis can utilize such as MICROSOFT
Figure A200780022369D0008101255QIETU
SDK (Software Development Kit) such as VISUAL STUDIO are carried out.During dynamic software analysis, analyze when carrying out analyzed software or its part and carrying out operation.The result of dynamic software analysis can comprise time sequence information, such as for example carrying out an operation and/or moving the needed time quantum of a part (fragment) of analyzed software.Exemplary dynamic software analysis tolerance comprise call the frequency that is performed, carry out the needed experience time of a function, with the definition of the method for virtual call spot correlation connection with whether be invoked at when carrying out allocate memory.
In an example embodiment, use is called the frequency that is performed and is come the static analysis performance checking that the refinement height is deterministic and frequently excited.In this case, it is favourable the result being narrowed down to the evaluating objects group of frequently being called.The time of repairing the item that does not often call does not guarantee this benefit, because the increment type performance gain is very little.Code changes also introduces the risk of degenerating, and this is the result to be concentrated on another reason of the most significant group.
In an exemplary scene, it is performance-sensitive that the user may want to specify a method or function.That is this method or call and in specific time threshold, to carry out.Can utilize the execution needed practical experience time of function to determine when operation, whether the execution time surpasses this threshold value.And, can be in aasubsequent staticaanalysis issue result in service.This static analysis can also indicate any point of invocation that the time that is spent in carrying out is responsible for.
The static analysis that needs the visit specific call site to realize can not be operated the virtual call point.Can determine to expand this static analysis with the definition of the specific concrete grammar of virtual call spot correlation connection and with it.Can provide such as the information such as specific subclass that are tied to virtual call point to this static analysis.
In an exemplary scene, may need to understand the term of execution whether distributed storer.Determining whether to have taken place memory allocation statically may be impossible very difficult and in some cases.For example, can not determine the memory allocation that causes because of to calling of virtual method via static analysis.Can dynamically collect this information and provide it to aasubsequent staticaanalysis.
In step 16, determine whether to have stored tolerance from previous dynamic software analysis.This tolerance can be about the same software entity of dynamically being analyzed, or about a version of analyzed software entity.For example, during code development, the first version of analysis software assembly and selected (or all) tolerance that therefrom obtains can being stored in the storer dynamically.Then, can make a change, obtain another version of this software module software module.(for example, step 14) can determine that (for example, step 16) stored from the tolerance to the performance analysis of the previous version of this software module when dynamically analyzing the later release of this software.Can comprise tolerance from the tolerance of previous performance analysis from performance analysis previous expansion and/or that do not expand.That is, from the tolerance of previous performance analysis can comprise coming the performance analysis that free static analysis expands tolerance, come the tolerance of the performance analysis that free previous performance analysis expands, from tolerance or its combination of the performance analysis of not expanding.
In an example embodiment, the code of visiting other binary code of himself not analyzed is statically carried out static analysis.Yet if there are the data that dynamically obtain in those dependences, the static analysis of targeted binary code utilizes this information to verify its client's use.
If stored from tolerance (step 16) to the previous dynamic software analysis of a same software entity or an one version, the tolerance of being stored then in step 18 retrieval.Tolerance can be stored on any suitable medium, such as for example, and magnetic storage, optical memory, hard disk, semiconductor memory, flash memory etc.In step 20, tolerance and the current performance analysis of being retrieved integrated to expand present analysis.
In an example embodiment, for the purpose of efficient, realized limiting the mechanism of collecting when moving based on static analysis.For example, the user can indicate this user interested in the ad hoc approach of particular type or a certain type.When operation, can forbid dynamic data collection fully, unless the code that proof is performed can arrive from the target that will be analyzed statically.
In step 22, storage is from the result's who expands tolerance, and this process advances to step 24.For example, during code development, the first version of software entity can comprise calling non-existent website when this first version is dynamically analyzed.Therefore, will be used as virtual call to calling of this website and treat, and during to the performance analysis of this first version, will estimate such as sequential and memory allocation isometry.Then, can finish this website, and to the subsequent dynamic analysis of this software entity will comprise such as sequential and memory allocation etc. with call the tolerance that this real network website is associated.
If do not store,, determine whether to have stored from tolerance to the previous staticasoftware analysis of a same entity or an one version then in step 24 from tolerance (step 16) to the previous dynamic software analysis of a same software entity or an one version.Can comprise tolerance from the tolerance of previous static analysis from static analysis previous expansion and/or that do not expand.That is, from the tolerance of previous static analysis can comprise coming the static analysis that free performance analysis expands tolerance, come the tolerance of the static analysis that free previous static analysis expands, from tolerance or its combination of the static analysis of not expanding.On software, carry out static analysis and do not carry out this software.Can on source code and/or object code, carry out static analysis.From the result of static analysis can comprise lines of code in the software for example, (the order complicacy is the extended measurements to the soundness of program and trust property to possible code error (for example, incorrect sentence structure), maintainability metrics, Program Semantics mistake, logic error, order complicacy (cyclomatic complexity).The order complicacy provides and can be utilized to the single ordinal number that the complicacy with other program compares.) or the like.Another example static analysis tolerance can comprise the easy configuration details static state setting of collecting when indicating whether to should be binary code, type, method enables analysiss/operation.Another example static analysis tolerance can comprise code complexity.
If the tolerance of the static analysis before the storage (step 24) then in step 32, does not provide the result of current performance analysis.If the tolerance of the static analysis before having stored (step 28) then in step 26, is retrieved these tolerance.In step 28, the tolerance retrieved and the result of current performance analysis are integrated to expand current performance analysis.In step 34, store tolerance, and provide these results in step 32 from integrated result.
